The operation unit 120 is a member for operating the body composition meter 10.
The storage unit 122 includes a RAM (Random Access Memory) 122a, a ROM (Read Only Memory) 122b, and a rewritable memory 122c. The ROM 122b is a non-volatile memory, and stores various programs for causing the CPU 126 to execute various processes and an arithmetic expression for calculating weight.

  The interface 191 is an interface for connecting the function adding device 301 to the body composition monitor 10. As in this example, when the function adding device 301 is configured as a USB memory medium, the interface 191 is configured as a USB interface. In the example shown in FIG. 2, the function addition devices 301-1, 301-2, and 301-3 are connected to the body composition meter 10 through the interface 191 so as to communicate with each other. That is, the interface 191 functions as a plurality of connection terminals that connect the recording medium (in this example, the function adding device 301) so as to be communicable.

Hereinafter, an example of the measurement process of the body composition data by the body composition meter 10 according to the first embodiment of the present invention will be described. FIG. 3 is a view showing a flowchart of a body composition data measurement process by the body composition meter 10 according to the first embodiment of the present invention.
First, when the body composition meter 10 is turned on by the operation of the operation unit 120 by the measurement subject, the CPU 126 activates the body composition meter 10 and causes the display unit 202 to display an initial screen. The initial screen is, for example, a mode setting operation screen. Here, when the “body composition measurement mode” is selected and determined by the operation of the operation unit 120 by the measurement subject, the CPU 126 sets the body composition meter 10 to the “body composition measurement mode”. The “body composition measurement mode” is a mode for measuring the body composition data of the measurement subject.

  When the body composition meter 10 is set to the body composition measurement mode, the CPU 126 first sets “body characteristic information” relating to the living body of the measurement subject (step S1). “Body characteristic information” is information indicating the physical characteristics of the measurement subject input to the body composition meter 10 by the operation of the operation unit 120 by the measurement subject, for example, information such as height, weight, age, and sex. It is. When the body characteristic information is input by the measurement subject, the physical characteristic information is stored in the rewritable memory 122 c of the storage unit 122 in association with the identifier related to the measurement subject. In step S <b> 1, the CPU 126 reads the body characteristic information related to the measurement subject from the rewritable memory 122 c of the storage unit 122 and sets it as the body characteristic information in the body composition measurement process. That is, the CPU 126 functions as an information setting unit that sets second information indicating the physical characteristics of the measurement subject.

  Subsequently, the CPU 126 reads “information indicating the type of body composition data” that can be calculated by the function adding device 301 from the function adding device 301 connected to the interface 191, and displays the “body composition data” indicated by the information. Type "is presented to the user (step S2). Specifically, the CPU 126 turns on the function display unit 161 corresponding to the body composition data that can be calculated by the function adding device 301 connected to the interface 191. The user can easily know the type of body composition data that can be measured by the body composition meter 10 only by visually recognizing the lighting state of the function display unit 161.

  In the example shown in FIG. 1 and FIG. 2, the function addition device 301-1 in which the calculation program for calculating the “body fat percentage” is recorded, and the function addition device 301- in which the calculation program for calculating the “lean body mass” is recorded. 2 and a function addition device 301-3 in which a calculation program for calculating “basal metabolic rate” is recorded is connected to the interface 191. Accordingly, the status display section 151 corresponding to these interfaces is turned on, the function display section 161 with “1” associated with body fat percentage measurement, and “2” associated with lean body mass measurement are displayed. The indicated function display 161 and the function display 161 indicated by “3” associated with the basal metabolism measurement are turned on.

  The person to be measured refers to the type of measurable body composition data presented by the body composition meter 10 in the process in step S2, and the item (desired body composition data) that he / she wants to actually measure by operating the operation unit 120 Type). The CPU 126 sets the type of body composition data selected by the measurement subject as an item for actual measurement (step S3).

  Here, the person to be measured is placed on the placement portion 102 of the body composition meter 10, the left foot of the person to be measured is placed on the energizing electrode 104a and the measuring electrode 104c, and the energizing electrode 104b and the measuring electrode The right foot of the measurement subject is placed on 104d. In this state, the CPU 126 measures the weight W of the person to be measured using the weight sensor unit 112 (Step S4), and measures the bioimpedance Z using the voltage measurement circuit 110 (Step S5). The body weight W measured by the weight sensor unit 112 and the bioelectrical impedance Z measured by the voltage measurement circuit 110 are temporarily stored in the RAM 122a of the storage unit 122 after being transmitted to the CPU 126. That is, the CPU 126, the weight sensor unit 122, and the voltage measurement circuit 110 function as a measurement unit that measures the biological impedance of the measurement subject.

Subsequently, the CPU 126 reads out an arithmetic program from the function adding device 301 (step S6). In other words, the CPU 126 is a recording medium (function adding device 301 in this example) on which at least one first information (calculation program in this example) required for calculation of body composition data indicating a specific type of body composition is recorded. In the body composition meter that calculates one or a plurality of types of body composition data using one or a plurality of data, it functions as an information acquisition unit that acquires one or a plurality of the first information from each of the one or a plurality of recording media .
Specifically, in this example, a calculation program for calculating “body fat percentage” is read from the function addition device 301-1 and a calculation program for calculating “lean fat mass” is read from the function addition device 301-2 to add a function. A calculation program for calculating “basal metabolic rate” is read from the apparatus 301-3.

  Then, the CPU 126 calculates body composition data from the body characteristic information and the bioelectrical impedance Z by executing the calculation program read in step S6 (step S7). In other words, based on the one or more pieces of the first information (calculation program in this example), the second information (body characteristic information in this example) acquired by the information acquisition unit, and the bioelectrical impedance, It functions as a calculation unit that calculates body composition data indicating the type of body composition corresponding to each of the one or more pieces of the first information. Hereinafter, the process in step S7 will be specifically described.

<Measurement of body fat percentage>
The CPU 126 executes a calculation program for obtaining the body fat percentage% Fat read from the function adding device 301-1. Thereby, the calculation of the following arithmetic expression (Formula 1) is executed, and the body fat percentage is calculated (estimated).
% Fat = f1 · Z · W / H ² −f2 (Formula 1)
However, f1 and f2 are coefficients and are values determined appropriately by multiple regression analysis. Z is the biological impedance of the person to be measured, W is the weight of the person to be measured, and H is the height of the person to be measured. Here, the weight W and the height H correspond to the body characteristic information described above.

<Measurement of lean mass>
The CPU 126 executes a calculation program for obtaining the lean mass FFM read from the function adding device 301-2. Thereby, calculation of the following arithmetic expression (Formula 2) is executed, and the lean mass is calculated (estimated).
FFM = WW-% Fat / 100 (Formula 2)
However,% Fat is a value calculated by (Equation 1).

<Measurement of basal metabolism>
The CPU 126 executes a calculation program for obtaining the basal metabolic rate BMR read from the function adding device 301-3. Thereby, the calculation of the following arithmetic expression (Formula 3) is executed, and the lean mass is calculated (estimated).
Basal metabolic rate BMR = p1 · FFM ² + p2 · FFM + p3 · (1 / Age) + p4 (Formula 3)
However, the coefficients p1 to p4 are values appropriately determined by multiple regression analysis, Age is the age of the person to be measured,% Fat is a value calculated by (Equation 1), and FFM is obtained by (Equation 2). This is a calculated value.

  When the calculation of the body composition data in step S7 ends, the CPU 126 stores the body composition data in the RAM 122a of the storage unit 122 (step S8) and displays it on the display unit 202 (step S9), and the body composition measurement process Exit. In this example, the values of the body fat percentage% Fat, the lean body mass FFM, and the basal metabolic rate BMR are displayed on the display unit 202 in step S9. Note that not only the body composition data calculated in step S7 but also the body weight measured in step S4 may be displayed on the display unit 202 in step S9 together with the body composition data.

As described above, according to the first embodiment of the present invention, it is possible to provide a body composition meter and a body composition measurement system that can customize the measurement function according to the needs of each user.
That is, the user simply purchases the function adding device 301 related to the measurement of desired body composition data, and connects it to the body composition meter 10 as a platform, so that the body composition meter 10 having only the minimum necessary functions can be obtained. Can be configured. Therefore, the body composition meter 10 having high cost performance for both the user and the manufacturer is realized. In addition, when it becomes necessary to newly expand the measurement function after purchasing the body composition analyzer 10, the measurement function can be easily expanded.
Furthermore, since the body composition meter 10 is a platform having a minimum measurement function, the body composition meter 10 can be configured as a simple and rich design platform.
In addition, a body composition meter 10 that has already been purchased by the user has been provided with a measurement function for body composition data that was not assumed at the time of sale of the body composition meter 10 or body composition data that has become newly measurable due to technological advances. It becomes possible to add easily.

By the way, the body composition meter is often used in general households. When the body composition meter is used in a general household, the body composition meter records and manages body weight data and body composition data for each person to be measured. By applying the body composition meter 10 and the body composition measuring system 1 according to the first embodiment of the present invention to such a body composition meter, for example, the following special effects can be obtained. That is, each body member (for example, father, mother, children, grandparents, etc.) can provide the body composition meter 10 with the function of measuring the body composition data of the type desired to be measured without omission. .
Furthermore, according to the body composition meter 10 and the body composition measuring system 1 according to the first embodiment of the present invention, for example, a grown-up child comes into full-scale sports and desires to measure muscle mass at a specific part. Even if it becomes a case, that is, when a new type of body composition data measurement function is required as the child grows, such a special body composition data measurement function is provided. There is no need to purchase a new body composition meter, and such special body composition data can be measured by additional purchase of only the function adding device 301.
Thus, in the body composition meter 10 according to the first embodiment of the present invention, a plurality of users (measured persons) using the body composition meter 10 desire different measurement functions, or the body composition meter 10 This is very useful when a new measurement function is desired after purchase of the product.
In the above embodiment, the body composition meter 10 has a function of measuring body weight, and the function addition device is used to calculate the “body fat percentage”, “lean fat mass”, and “basal metabolic rate”. Although an example of adding a function to be performed has been shown, the functions that can be added are not limited to these. In addition, for example, the body composition meter 10 has a function of measuring body weight and a function of calculating body fat percentage, and using a function adding device, a function of calculating “lean mass” and “basal metabolism”. The combination of the function provided on the main body side of the body composition meter 10 and the function that can be added using the function adding device is arbitrary.

<Modification>
Hereinafter, a body composition meter and a body composition measurement system according to a modification of the first embodiment of the present invention will be described. In order to avoid duplication of explanation, differences from the body composition meter and the body composition measurement system according to the first embodiment will be described. The body composition meter and body composition measurement system according to the modification of the first embodiment are mainly different from the body composition meter and body composition measurement system according to the first embodiment in the following points.
That is, in the body composition analyzer 10 according to the first embodiment, the body composition analyzer 10 executes the calculation program recorded in the function adding device 301 only when the function adding device 301 is connected to the interface 191. Body composition data can be calculated. On the other hand, in the body composition analyzer 10 according to this modification, when the function adding device 301 is connected to the interface 191, the CPU 126 of the body composition analyzer 10 reads out the operation program recorded in the function adding device 301, and the operation program Is stored in the storage unit 122.
That is, when the function adding device 301 is connected to the interface 191, the body composition analyzer 10 according to the present modification downloads the arithmetic program recorded in the function adding device 301 to the storage unit 122. That is, in the body composition analyzer 10 according to this modification, the storage unit 122 functions as a storage unit that stores one or a plurality of restriction release keys acquired from the function addition device 301.

  By the way, as in the first embodiment, each function adding device 301 also records “information indicating the type of body composition data” that can be measured by the calculation program together with the calculation program in association with the calculation program. ing. When the CPU 126 acquires the arithmetic program from the function adding device 301 and stores it in the storage unit 122, the CPU 126 also acquires “information indicating the type of body composition data” from the function adding device 301 and stores it in the storage unit 122.

The difference between the processing of the flowchart shown in FIG. 3 and the first embodiment is the processing of step S2 and step S6. First, in step S <b> 2, the CPU 126 turns on the function display unit 161 related to the type of body composition data indicated by the “information indicating the type of body composition data” stored in the storage unit 122. By visually recognizing the display of the function display unit 161, the user can easily know the types of body composition data that can be measured without connecting the function adding device 301 to the interface 191 at this time.
In step S6, the arithmetic program is read from the function adding device 301 in the first embodiment, but the arithmetic program is read from the storage unit 122 in the present modification. That is, in the present modification, the CPU 126 reads out from the storage unit 122 a calculation program associated with “information indicating the type of body composition data” indicating the type of body composition data set in step S3.

  In addition, in order to prevent the calculation program recorded in the function adding device 301 from being illegally downloaded to a plurality of body composition analyzers 10, the calculation program is erased after processing for prohibiting multiple downloads or after downloading. The processing to be performed may be performed on the arithmetic program in advance. Moreover, when permitting the download of the arithmetic program from the function adding device 301 to the specific number of body composition analyzers 10, a process for prohibiting the arithmetic program from being downloaded a number of times exceeding the specific number may be performed.

As described above, according to the modification of the first embodiment of the present invention, the same effects as those of the body composition meter and body composition measuring system according to the first embodiment can be obtained, and the following effects can be achieved. A meter and a body composition measuring system can be provided.
That is, according to the body composition meter and the body composition measuring system according to this modification, when the function adding device 301 is connected to the interface 191, the operation program recorded in the function adding device 301 is stored in the CPU 126 of the body composition meter 10. And stored in the storage unit 122. In other words, when the function adding device 301 is connected to the interface 191, the calculation program recorded in the function adding device 301 is downloaded to the body composition analyzer 10.
Therefore, for the function adding device 301 for which the calculation program has already been downloaded to the body composition meter 10, it is possible to save the trouble of connecting the function adding device 301 to the interface 191 each time body composition data is measured. . Moreover, the external structure of the body composition meter 10 at the time of measuring body composition data is simplified.

[Second Embodiment]
Hereinafter, a body composition meter and a body composition measurement system according to a second embodiment of the present invention will be described. In order to avoid duplication of explanation, differences from the body composition meter and the body composition measurement system according to the first embodiment will be described. The body composition meter and body composition measurement system according to the second embodiment are mainly different from the body composition meter and body composition measurement system according to the first embodiment in the following points.
That is, the body composition meter 10 according to the first embodiment described above employs a configuration in which the function adding device 301 is provided with an operation program for calculating body composition data, without being provided with the body composition meter 10. However, it is sufficient that the body composition meter 10 and the function adding device 301 cooperate to calculate body composition data, and the present invention is not limited to the above-described configuration.
Therefore, in the second embodiment of the present invention, execution of a plurality of calculation programs for measuring body composition data is stored in advance in the storage unit 122 (for example, ROM 122b) of the body composition meter 10 while restricting execution. The arithmetic programs that are restricted in execution are arithmetic programs that can be executed with the execution restrictions being released by the “restriction release key that designates a specific arithmetic program and instructs the cancellation of the execution restrictions”. . Here, the restriction release key is recorded in the function adding device 301. In this example, it is assumed that one restriction release key corresponds to one calculation program.

  Further, in the function adding device 301, together with the restriction release key, “information indicating the type of body composition data” that can be measured by the restriction release key is recorded in association with the restriction release key. When the body composition meter 10 is set to the “body composition measurement mode”, the CPU 126 displays the function related to the type of body composition data indicated by the “information indicating the type of body composition data” recorded in the function adding device 301. The part 161 is turned on. By visually recognizing the display of the function display unit 161, the user can easily know the types of body composition data that can be measured without connecting the function adding device 301 to the interface 191 at this time.

Hereinafter, an example of measurement processing of body composition data by the body composition meter 10 according to the second embodiment of the present invention will be described. FIG. 4 is a view showing a flowchart of a body composition data measurement process by the body composition meter 10 according to the second embodiment of the present invention.
Note that steps S11 to S15 in the flowchart shown in FIG. 4 are steps for performing the same processing as steps S1 to S5 described with reference to FIG. Therefore, in order to avoid duplication of explanation, the processing after step S16 will be explained.

When the measurement of the bioelectrical impedance Z by the voltage measurement circuit 110 is completed in step S15, the CPU 126 reads from the function adding device 301 a restriction release key that designates a specific calculation program and instructs the removal of the restriction on execution (step S16). ).
Specifically, in this example, the restriction release key for instructing the release of the restriction of the calculation program for calculating the “body fat percentage” is read from the function addition apparatus 301-1, and the “lean mass” is read from the function addition apparatus 301-2. The restriction release key for instructing the release of the restriction of the calculation program for calculating the calculation is read, and the restriction release key for instructing the release of the restriction for the calculation program for calculating the “basal metabolic rate” is read from the function adding device 301-3.

  Then, the CPU 126 reads out the calculation program instructed to release the restriction by the restriction release key read in step S16 from the storage unit 122, releases the execution restriction, and uses the body characteristic information and the bioelectrical impedance Z to calculate the calculation program. Is executed to calculate body composition data (step S17). The specific calculation process performed by executing the arithmetic program in step S17 is the same as the calculation process in step S7 of the flowchart shown in FIG.

  When the calculation of the body composition data in step S17 is completed, the CPU 126 stores the body composition data in the RAM 122A of the storage unit 122 (step S18) and displays it on the display unit 202 (step S19). The measurement process ends. Note that not only the body composition data calculated in step S17 but also the body weight measured in step S14 may be displayed on the display unit 202 in step S19 together with the body composition data.

Note that the calculation program stored in the ROM 122b may be a calculation program incorporating a locking / unlocking process for releasing the execution restriction when a restriction release key is input. In the case of such a configuration, the restriction release key used for the unlocking process related to the specific calculation program may be recorded in the function adding device 301.
As described above, according to the second embodiment of the present invention, the same effect as the body composition meter 10 and the body composition measuring system 1 according to the first embodiment can be obtained, and the following effect can be obtained. The composition meter 10 and the body composition measuring system 1 can be provided.
That is, since the restriction release key is recorded in the function adding device 301, the recording capacity of the function adding device 301 can be reduced as compared with the case of recording the arithmetic program. Moreover, although the restriction release key is transmitted from the function adding device 301 to the body composition analyzer 10, the calculation program is not transmitted. If the arithmetic program is transmitted, if the arithmetic program is intercepted during the transmission, the arithmetic program may be analyzed or the arithmetic program may be diverted to an unauthorized device. However, since the restriction release key is only transmitted in the second embodiment, it is possible to prevent illegal acquisition of the arithmetic program that may occur due to the transmission of the arithmetic program.

<Modification>
Hereinafter, a body composition meter and a body composition measurement system according to a modification of the second embodiment of the present invention will be described. In order to avoid duplication of explanation, differences from the body composition meter and the body composition measurement system according to the second embodiment will be described. The body composition meter and body composition measurement system according to the modification of the second embodiment are mainly different from the body composition meter and body composition measurement system according to the second embodiment in the following points.
That is, in the body composition meter 10 according to the second embodiment, the body composition meter 10 uses the restriction release key recorded in the function adding device 301 only when the function adding device 301 is connected to the interface 191. Thus, the restriction on the execution of the arithmetic program stored in the storage unit 122 can be removed.
On the other hand, in the body composition analyzer 10 according to this modification, when the function adding device 301 is connected to the interface 191, the CPU 126 of the body composition analyzer 10 reads the restriction release key recorded in the function adding device 301 and The release key is stored in the storage unit 122.

That is, when the function adding device 301 is connected to the interface 191, the body composition analyzer 10 according to the present modification downloads the restriction release key recorded in the function adding device 301 to the storage unit 122. That is, in the body composition analyzer 10 according to the present modification, the storage unit 122 functions as a storage unit that stores one or more restriction release keys acquired from the function addition device 301.
By the way, as in the second embodiment, each function adding device 301 is also associated with “restriction release key” and “information indicating the type of body composition data” that can be measured with the restriction release key. Are recorded. When acquiring the restriction release key from the function adding device 301 and storing it in the storage unit 122, the CPU 126 also acquires “information indicating the type of body composition data” from the function adding device 301 and stores it in the storage unit 122.

The difference between the processing of the flowchart shown in FIG. 4 and the second embodiment is the processing of step S12 and step S16. First, in step S <b> 12, the CPU 126 turns on the function display unit 161 related to the type of body composition data indicated by the “information indicating the type of body composition data” stored in the storage unit 122. By visually recognizing the display of the function display unit 161, the user can easily know the types of body composition data that can be measured without connecting the function adding device 301 to the interface 191 at this time.
In step S16, the restriction release key is read from the function adding device 301 in the second embodiment described above, but the restriction release key is read from the storage unit 122 in the present modification. That is, in the present modification, the CPU 126 of the body composition analyzer 10 reads one or more restriction release keys stored in the storage unit 122 from the storage unit 122 in step S16.

  In addition, in order to prevent the restriction release key recorded in the function adding device 301 from being illegally downloaded to a plurality of body composition analyzers 10, the restriction release key is not permitted after a process for prohibiting multiple downloads or after downloading. The process to be deleted may be applied to the restriction release key in advance. In addition, when permitting the download of the restriction release key from the function adding device 301 to the specific number of body composition analyzers 10, a process of prohibiting the restriction release key from being downloaded more than a specific number of times may be performed.

As described above, according to the modification of the second embodiment of the present invention, the same effects as those of the body composition meter and body composition measuring system according to the second embodiment can be obtained, and the following effects can be achieved. A meter and a body composition measuring system can be provided.
That is, according to the body composition meter and body composition measuring system according to this modification, when the function adding device 301 is connected to the interface 191, the restriction release key recorded in the function adding device 301 is transferred to the body composition meter 10. Downloaded. Therefore, for the function adding device 301 for which the restriction release key has already been downloaded to the body composition meter 10, the trouble of connecting the function adding device 301 to the interface 191 every time body composition data is measured is saved. be able to. Moreover, the external structure of the body composition meter 10 at the time of measuring body composition data is simplified.

Note that this modification can be further modified as follows. That is, instead of storing the restriction release key acquired from the function addition device 301 in the storage unit 122, the calculation program that instructs the restriction release key to release the restriction when the restriction release key is acquired from the function addition device 301. An identifier indicating that the restriction is to be released may be attached. As a result, when actually calculating body composition data, the CPU 126 can specify the target arithmetic program for which the restriction on execution is to be released, so that it is not necessary to store the restriction release key in the storage unit 122. In this case, the process of step S16 in the flowchart shown in FIG. 4 becomes unnecessary.
Specifically, when the CPU 126 acquires the restriction release key from the function adding device 301, the CPU 126 reads out the arithmetic program designated by the restriction release key from the storage unit 122, and corresponds the identifier indicating that the restriction is released to the arithmetic program. Then, it is stored in the storage unit 122. In step S17, the CP 126 calculates body composition data by executing a specific calculation program associated with the identifier using the body characteristic information and the bioelectrical impedance.

[Third Embodiment]
Hereinafter, a body composition meter and a body composition measurement system according to a third embodiment of the present invention will be described. In order to avoid duplication of explanation, differences from the body composition meter and the body composition measurement system according to the first embodiment will be described. The body composition meter and body composition measurement system according to the third embodiment are mainly different from the body composition meter and body composition measurement system according to the first embodiment in the following points.
That is, in the first embodiment, the body composition meter 10 is provided with an interface 191, and the function adding device 301 is directly connected to the body composition meter 10 through the interface 191. On the other hand, the body composition measuring system 1 according to the third embodiment includes a body composition meter 10, a function adding device 301, and an operation program connected to the function adding device 301 and recorded in the function adding device 301. Information transmitting apparatus 400 (details will be described later with reference to FIGS. 5 and 6).
In the present embodiment, the body composition meter 10 is provided with a communication unit (not shown) that enables wireless or wired communication, and the communication unit receives the arithmetic program transmitted from the information transmission device 400. With this configuration, it is not necessary to connect the function adding device 301 to the body composition monitor 10. Therefore, the appearance configuration and system configuration of the body composition meter 10 can be further simplified.
Examples of the communication unit provided in the body composition meter 10 include a communication module that enables wireless communication with the information transmission device 400. Specifically, for example, a communication module that connects the body composition meter 10 and the information transmitting apparatus 400 by short-range wireless communication according to the Bluetooth (registered trademark) standard, and the body composition by a wireless LAN (Local Area Network). The communication module etc. which connect the total 10 and the information transmitter 400 with Wi-Fi (trademark) can be mentioned.

By the way, as in the first embodiment, each function adding device 301 records, together with the calculation program, “information indicating the type of body composition data” that can be measured by the calculation program in association with the calculation program. ing. Therefore, information indicating the type of the body composition data is also transmitted from the transmission device 400 to the body composition meter 10 together with the calculation program.
When the CPU 126 receives the calculation program and the “information indicating the type of body composition data” transmitted from the information transmitting device 400 by the communication unit, the CPU 126 sets the type of body composition data indicated by the “information indicating the type of body composition data”. The function display unit 161 is turned on. Thereby, even if the information transmission apparatus 400 is located in a place away from the body composition meter 10, the person to be measured can add to the body composition meter 10 only by visually recognizing the function display unit 161. It is possible to easily know the function and the function actually added at the present time.
